- Description:
- The LangChain Agent Protocol is a framework-agnostic specification for
serving Large Language Model (LLM) agents in production. It defines
standardized APIs for executing agents (Runs), managing multi-turn
interactions (Threads), and handling long-term memory (Store).
The protocol includes a thread-centric streaming layer for observing and
controlling live agent executions, featuring support for message deltas,
tool lifecycle events, and human-in-the-loop interactions.
This package provides the Python bindings and server stubs for the
protocol, enabling developers to build and interact with interoperable
agentic applications using strongly typed payloads.
